WASHING-MACHINE.

SPECIFICATION forming part Of Letters Patent NO. 690,410, dated January 7, 1902.

Application filed J111y16,l9O1. Serial. No. 68,294. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE B. DoWsWELL, a citizen of Canada, residing at Hamilton, in the county of Wentworth and Province of Ontario, Canada, have invented certain new and useful Improvements in Washing-Machines; and I'do hereby declare the following to be a full, clear, and exact description ofithe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in washing-machines comprising a water-box containing a pivotal convex oscillatory clothes-rubber and a concave reciprocating clothescompressor connected together in such a manner to afford end yielding of the compressor to the clothes between the slatted convex face of the clothes-rubber and the slatted concave face of the clothescompressor.

The objects of my invention are, first, to provide a 'machine which is capable of washing heavy-and light clot-hes at the same time in a most efficient manner; second, to provide means for allowing end yielding to the compressorto suit any possible uneven displace- 'ment of the clothes between the rubber and compressor, and, third, to afford facilities for washing and compressing the clothes in an even manner when the clothes are unevenly disposed, as heavy fabric on one side of the machine and light fabric on the opposite side I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a sectional side elevation of the washing-machine in its completeness. Both sides of the machine are identical with each other in every detail of construction. Fig. 2 is a plan of the same, the upper mechanism and partial covering of the box being removed to show more fully the interior. Fig. 3 is an enlarged detail side elevation of the connected parts of one side of the oscillatory rubber,

and the reciprocatory compressor. Fig. 4 is an enlarged detail side elevation of the same connecting part of the oscillatory rubber as in Fig. 3 and detached; Fig. 5 is an enlarged detail side elevation of the same connecting part of the reciprocatory compressor as in Fig. 3 and detached. Fig. 6 is an enlarged detail end elevation of a detached headed coupling-pin which when in position couples or connects the sides of the oscillatory rubber with the arms of the reciprocatory compressor. Fig. 7 is an'enlargeddetailplan of the connection of one side of the oscillatory rubber with the arm of the reciprocatory compressor.

Similar characters refer to similar parts throughout the several views.

In the drawings the water-box of the machine is indicated by A, the oscillatory slatted convex clothes-rubber by B, and the slatted concave reciprocatory clothes-compressor by O. The clothes-rubber B is capable of oscillating on the centers D of the sides of the box A and is oscillated by means of the side levers E with transverse handle F. These levers are ,fulcrumed on the centers of the rigid side brackets H, which are secured to the box A. Connecting-rods J connect the opposite end of the levers E with the sides of the clothes-rubber B to oscillate said rubber B when the handle F, together with the side levers E, are operated in the usual manner.

The reciprocating clothes-compressor C has arms 2 extending toward the oscillatory rubber B. These arms 2 have reduced end extensions or shanks K, which are capable of sliding through the openings 5, which are through the heads N of the connecting-pins P, which pass loosely through the bosses 4 of the sides of the oscillatory rubber B and are held in position by cotter-pins R. The pins P slightly rotate or oscillate when the ma chine is in operation. The shanks K of the arms 2 of the compressor 0 pass loosely through the holes or openings 5 of the heads N of the pins P and extend beyond sufficiently to contain proper lengths of spiral tension springs S, which coil around said shanks K. The shoulders 6 of the shanks K engage with one side of the heads N, and one end of the tension-sprin gs S engages with the other side of said heads. The'springs S are held in position on their respective shanks K by means of adjustable nuts T. These nuts T are for the purpose of allowing more or less tension to the springs S; therefore more or less yieldment or adjustment of the compressor. These springs S are very capable and efficient in allowing end yielding to the arms 2 of the clothes-compressor C, for instance,when heavy clothes, such as a blanket, should gather on one side of the machine and light fabric should gather on the opposite side of the machine and between the convex clothes-rubber B and the concave clothescompressor 0.

When the machine is in operation, the spring S in the side of the machine in which the heavy clothes have gathered will yield to afford greater distance between the clothesrubber B and the face of the clothes-compressor C and allow the opposite end of the compressor to compress the light clothes also. This feature is very important.

In reference to the mechanism connecting the clothes-rubber B with the clothes-compressor C it will be obvious that the said connected parts have a rotary reciprocating movement, as also the pins P, at the same time and in the opposite direction to the said connected part of the rubber B at each stroke or movement of the handle-levers of the machine.

U represents side hanging rods with pivoted connection to the sides of the box A and to the sides of the clothes-compressor C to support the compressor in its reciprocating movement. This movement of the compressor C is attained by means of its arm connection to the oscillatory clothes-rubber B, as described, when the same is operated as set forth.

The principal and most important part of my invention comprises the connection of the convex oscillatory clothes-rubber B with the concave reciprocating clothes-compressor C by means of mechanism, as set forth, to allow a proper yielding spring pressure to said clothes-compressor.

I am aware that in washing-machines, wa-

ter boxes ortubs, oscillatory convex clothesrubbers, reciprocating concave clothes-compressors with arms connected to said oscillatory rubber, and also means for allowing side adj ustment to the said concave clothes-compressor, and mechanism for operating the ma- ,chine are not new. These I do not claim broadly; but I What I do claim as my invention, and de= sire to secure by Letters Patent, is-- 1. In a washing-machine, a convex oscillatory clothes-rubber, a concave reciprocatory clothes-compressor provided with arms ex tending toward the clothes-rubber, shanks extending from the end of the arms, pins jonrnaled to the ends of the clothes-rubber, said shanks extending through said pins,spiral springs on said shanks to allow end yielding to the arms of the clothes-compressor, sub stantially as described and set forth.

2. In a washing-machine, a convex oscillatory clothes-rubber, a convex reciprocatory clothes-compressor provided with arms ex tending toward the clothes-rubber, shanks extending from the end of the arms, pins jonrnaled to the ends of the clothes-rubber, said shanks extending through said pins,spiral springson said shanks, and nuts on the ends of said shanks to engage the ends of said springs, to allow certain end yielding to the arms of the clothes-compressor, substantially as described and set forth.

In testimony whereof I atfix my signature in presence of two witnesses.
